I was thinking on trying some .40 /185 or .40/200 Leighs after I start on the Speers with some loose t7 powder and was confused on if the primer I select would have much different results
It mostly depends on which powder you are shooting and the design of your breech plug.
I am a 90% T7 shooter and I really like and trust the powder. I do shoot BH on occasion and mostly for testing purposes.
Most of the time when I am shooting - I do shoot a Win T7 primer. The only time I moght make a switch is during hunting season - i would switch to a Remington 209-4 primer. These are no longer avaiable but they were designed for the 410 shot gun shell. They are a bit hotter than the the T7 primer but yet cooler than the w209.
A lot of time primer selection really depends on what is available locally. Luckly I do a lot of trap shooting also so getting primers is not a real problem.
